Sayuri Kinniku (キン肉小百合,Kinniku Sayuri) is the mother of Kinnikuman, wife of Mayumi Kinniku, and the 57th Queen of Planet Kinniku. She is usually depicted as a typical long-suffering, loving mother character, but she has been known to transform into a violent fan during her sons matches, even to the point of using her husband to show Kinnikuman which moves to use. She has the ability to grow large like her son, as evident from the time she masqueraded as him in order to fight Kaijū and redeem his image. In the anime, she is very jealous of Mari, because Kinnikuman takes more attention on his love interest than his mother. In the manga and first anime she is typically referred to as Mama, but in the Throne Arc anime she is called by her real name. In both anime, she was listed in the credits as Queen Kinniku (キン肉王妃,Kinniku Ōhi). By Kinnikuman Nisei she has died, leaving Mayumi a widower.

Prisman's trademark technique was the deadly Rainbow Shower, where he channeled sunlight through his body into a beam that could destroy any Chōjin's body. He first demonstrated this on Kinnikuman Zebra. Prisman first saw action in the ring in a six-man tag team match that was himself, Super Phoenix and Mammothman against Kinnikuman Soldier, Buffaloman and Brocken Jr. Learning of Prisman's Rainbow Shower, Brocken stripped himself of his Chōjin power in order to use his body to shield Ataru from it. Shortly after, he, Phoenix, and Mammothman ganged up on Brocken, but Brocken regained his Chōjin Body and shattered Prisman's head with a Bremen Sunset on one of the kinshachi statues on Nagoya Castle. Immediately after, Brocken fell to his death into the canyon below, motivating Ramenman to train fiercely for a showdown with Prisman in the finals in Osaka Castle.

The two of them met in a Jungle Big Gym Skyscraper Death Match (ジャングル・ビッグ・ジム摩天楼デスマッチ,Janguru Biggu Jimu Matenrou Desumatchi), before which Prisman used his Rainbow Shower to destroy the ring attire of Ashuraman (who had sacrificed himself so that Team Kinnikuman could make it to the second match). Though Prisman hit Ramenman with the Rainbow Shower numerous times, he survived each hit and continued to fight back, using a few of his 102 Chōjin Attacks. After Ramenman was able to return the Rainbow Shower it looked as though he'd win, Phoenix had Prisman stand on the middle section of black bars and pulled a lever, causing all but the black bars to fall to the ground. However, Ramenman used the last of his power to jump back up and shatter Prisman's body the Kowloon Wall Drop, destroying him and avenging Brocken Jr.

Satan Cross (Hidetoshi Nakamura) used to be known as Samson Teacher, Ashuraman's childhood mentor in the demon world he was a bald looking man with four arms. It is implied that Samson Teacher is also a demon and a resident of the demon world, however he had a kind heart, crying after seeing a slaughtered animal, and tried to teach Ashuraman that demons don't have to be evil. During an exercise, a child Ashuraman fell into some rapids, so Samson Teacher saved him but lost his grip on a rock and fell down a waterfall, Ashuraman believed Samson Teacher to be dead at this point, and for the first time experienced sadness and cried. When Samson Teacher awoke he learned that he had brutally lost his legs from the rapids, but the God of Intelligence offered him the parasite Satan Cross, which would grant him his mobility and great power, if he would become the evil god's servant. He accepted and went by the name Satan Cross and lived as a bounty hunter. As Satan Cross he was a four-armed, and four-legged able to split into two. Years later, the god of Intelligence came to him again, this time so Satan Cross could repay the favor. The god of Intelligence wanted him to compete as a member of Kinnikuman Super Phoenix's team during the Survivor Match to see who would ascend the throne of Planet Kinniku, Super Phoenix was possessed by the evil god of intelligence and was trying to over throne Kinnikuman.

Satan Cross' first match was against The Ninja during the semifinals in Nagoya Castle, in which he demonstrated his Western Ninjitsu abilities. He eventually killed The Ninja splitting his chest open as Satan Cross separated into two chojin to do his Triangle Dreamer technique which is basically a romero special done in the air by two people turning away from each other causing the opponent's chest to split open. Satan Cross then went up against Ashuraman himself. During this fight he revealed his true identity, which affected Ashurman's performance and allowed Satan Cross to counter most of his techniques (most of which he had taught Ashuraman in the first place). Eventually, Ashuraman's desire to avenge The Ninja conquered his fear of hurting his trainer and he drove Satan Cross into the wall with a super-powered Ashura Lightning Strike. However, as they fell to the ground, Satan Cross applied the Triangle Dreamer, knocking Ashuraman out and causing the fight to end in a draw.

Satan Cross then fought Kinnikuman himself in a Magic Ring Equipment Death Match (魔法陣リング装着デス・マッチ,Mahou-jin Ringu Souchaku Desu Matchi) during the finals in Osaka Castle. During the fight, Ashuraman arrived and supported Kinnikuman, showing Satan Cross that his student had finally learned all of the lessons of kindness he had tried to teach him. This caused a power struggle between Satan Cross and his parasite to control his mind. Kinnikuman eventually defeated him with a Complete Muscle Spark, destroying only the parasite's head and allowing Satan Cross to die as the kind-hearted Samson Teacher.

Although this story has had some continuity errors removed in recent reprints, it still does not fit in well with Kinnikuman Nisei canon.

Kevin Mask is the son of Robin Mask and later a major character in Kinnikuman Nisei. He appears in the original printing as a child sized duplicate of Robin Mask and refers to Robin as "Tou-san" (父さん,father), but in the Remix he is changed to look more like he does in Nisei and refers to Robin as "Daddy". His presence in the story is one of its biggest continuity errors, as the story takes place 8 years after the Survivor Match and his starting age in Nisei (18) implies that he has not even been born yet.

The Kaijū Extermination chapters of Kinnikuman featured several monsters that destroyed portions of Japan or attempted to capture the main characters.

Kinkotsuman

Iwao (イワオ) (Rocky Slabb in the English dub of Nisei) is a rock Kaijū who first appears at an amusement park and is subsequently defeated by Kinnikuman. He returns when Kinnikuman is being interviewed by Natsuko and plans to beat him up in front of her and ruin his image. His first attempt is interrupted by Kappatron so he tries to take Natsuko hostage, but he is still easily defeated by Kinnikuman. He then takes on the role of Kinkotsuman's sidekick and helps him with all of his attempts to destroy Kinnikuman. They seemingly turn good after the Chōjin Olympics, but return as villains during the American Tag Tournament. In the anime, the two of them eventually join up with Detective Gobugari and act as Kinnikuman's main cheering squad. In Ultimate Muscle, he was renamed Rocky Slabb.

Iwao is not that bright and frequently copies Kinkotsuman's laugh and speech pattern. For example, he frequently says dawasa (だわさ) (which Kinkotsuman often ends his sentences with) as a single sentence, seemingly meaning "I agree". This annoys Kinkotsuman and often prompts him to bop Iwao on the head. Iwao also refers to Kinkotsuman as sensei. He is voiced by Masaharu Satou in Kinnikuman, and Yasuhiko Kawazu in Kinnikuman: Scramble for the Throne.

Nachiguron (ナチグロン) is a weak Kaijū that is afraid of humans. Kinnikuman is dispatched to fight him, but realizes Nachiguron is harmless and lets him go. Originally 60 m tall, he shrinks down to around 1 m and moves in with Kinnikuman and Meat. Meat initially objects to the idea, already having to take care of one big baby (Kinnikuman), but agrees if Nachiguron will take care of himself. He gives Nachiguron a special whistle to blow if he ever gets in trouble and sends him out to get the groceries. Nachiguron is then confronted by the Kaijū Yakuza for siding with Kinnikuman. He almost blows the whistle, but instead decides to take care of himself. He shows up again from time to time cheering on Kinnikuman or serving as referee, but is not seen again after the Chōjin Olympics. In the anime however, he first appears during the Chōjin Olympics as Zangyaku-seijin's cowardly minion, but eventually sides with Kinnikuman. He then takes on the role of Kinnikuman's second sidekick and is frequently seen with Meat throughout the rest of the anime. Nachiguron is bald when he first appears, but in the next chapter he has shaggy blonde hair which is his hairstyle for the remainder of the series. In addition to his cowardice, he is also a very loud snorer. He is named after the Nachiguro stones. He is voiced by Keiko Yamamoto in Kinnikuman, and Naomi Nagasawa in Kinnikuman: Scramble for the Throne.

Okamarasu (オカマラス) is an Okama Kaijū who first appears as the antagonist of the first pilot chapter. He later reappears in the first serialized chapter as one of the invading aliens and again as one of Kinkotsuman's minions. He appears to have a slight crush on Kinnikuman. His feelings for Kinnikuman lead him to allow Kinnikuman to escape from Kinkotsuman's prison. He is voiced by Sanji Hase.

Eraginesus (エラギネス) is a lizard Kaijū who first appears as the antagonist of the second pilot chapter. He later reappears in the first serialized chapter as one of the invading aliens and again as one of Kinkotsuman's minions. He is voiced by Kouji Totani.

Abdullah (アブドーラ) is a Kaijū based on Abdullah the Butcher who first appears in the first serialized chapter as one of the invading aliens. He later reappears attacking the Japanese Diet building when Terryman first appears. He and Mouko-Seijin later team up to fight Kinnikuman and Terryman in a tag match to decide who is better between Chōjin and Kaijū. In the anime he is renamed Abdudullah (アブドドーラ), and the one that appears after Terryman defeats the first one is said to be Abududullah Jr.

Acrobat-seijin (アクロバット星人,Acrobat Alien) is an acrobat Kaijū who first appears in the first serialized chapter as one of the invading aliens. Kinnikuman claims the best defense against his acrobatic moves is finger pops. A character resembling Acrobat-seijin appears in Kinnikuman Nisei: Ultimate Chōjin Tag Arc among the pile of tag teams killed by the Time Chōjins, but it is unknown whether or not it is him.

Gorizaemon (ゴリザエモン) is a gorilla Kaijū whose specialty is making his nose drip on command. Kinnikuman hires him to kidnap pop idol Nana Takahara so Kinnikuman can save her and win her over, but he falls for Nana and fights back. Kinnikuman eventually defeats him. He has a sister named Gonta. He is voiced by Kazuhiko Kishino.

Nessie (ネッシー) is the legendary mysterious creature that dwells in Loch Ness. When Kinnikuman first hears of her and that she is believed to be 20 meters tall (shorter than his giant form), he decides challenge her to a fight on live TV. Unfortunately, she turns out to be much larger than his giant form and defeats him with a mere lick on the cheek. In the anime, she first plays around with him before knocking him into space. When Kinnikuman gets a garlic boost from Meat and tries to fight back, she ends up swallowing him and then later pooping him out as she leaves.

Shiek-seijin (シーク星人,Alien Shiek) is a sheikh Kaijū who first appears in the first serialized chapter as one of the invading aliens. He later reappears and attacks Tokyo, prompting Kinnikuman to go off and fight him despite not being Japan's official hero anymore. This in turn prompts Terryman to quite his businesslike ways and fight purely for the sake of justice. He is voiced by Kazuhiko Kishino.

Franky (フランキー) is a Kaijū who kidnaps two of Mari's students. Kinnikuman tries to save them, but they prefer Franky and refuse to be saved. This comically results in Franky having to protect the children from an angry Kinnikuman. Before he can make his mother proud by becoming the first popular Kaijū, Meat lures the children away with chocolate and defeats Franky. He is voiced by Tetsuo Mizutori.

Zangyaku-seijin (ザンギャク星人,Brutal Alien) is an alien whose father was killed by Kinnikuman while trying to take over the Earth. He has a gun for a hand and speaks with a Kyūshū dialect. He hijacks a bus with Kinnikuman, Meat, Mari, and the school children and demands to fight Kinnikuman. Kinnikuman refuses until he lets the children and Mari go (Meat stays behind on his own accord). He is defeated when Kinnikuman's Kinniku Flash causes the bus to explode. Kinnikuman gets good press over this fight (the headlines reading "Kinnikuman Miraculously Saves the Day"), but the children are ungrateful because they have to walk to school now thanks to him. His appearance also marks the debut of Detective Akaiwa (Gobugari in the anime). In the anime, he appears with Nachiguron as his minion during the 20th Chōjin Olympics. He is voiced by Daisuke Gouri.

Kappatron (カッパトロン) is a Kappa Kaijū who attacks Tokyo while Natsuko is interviewing Kinnikuman. He is ultimately defeated by Terryman because Kinnikuman wasted time reminding Natsuko to take pictures. It could be said that Kappatron played an important role in Terry and Natsuko's relationship, as his rampage provided them with a chance to meet. He was also the first fan submission Kaijū. He is voiced by Kouji Totani.

Daibutsura (ダイブツラー) is a Daibutsu Kaijū who lives in the ocean. Once every 50 years, he rises from the ocean and abducts beautiful women in order to peek at their vulva. He is defeated by Kinnikuman's Yoshinoya Kinniku Flash.

Dai King (ダイキング,Great King) is a vampiric Kaijū who kidnaps citizens of Planet Kinniku in order to fight Kinnikuman. He learns of Kinnikuman's weakness to milk and uses it to his advantage. Kinnikuman eventually gets a garlic boost from Meat's sister Rare and defeats him.

Mouko-seijin (猛虎星人,Fierce Tiger Alien) is a saber-wielding Kaijū modeled after Tiger Jeet Singh who teams up with Abdullah to fight Kinnikuman and Terryman in a tag match to decide who is better between Chōjin and Kaijū. Kinnikuman defeats him with a Back Drop. A character with the name Mouko-seijin appears in the first Kinnikuman movie, although he looks entirely different. He is voiced by Kouji Yada.

Sokonashi-seijin (底無し星人,Bottomless Alien) is an alien who devours everything in his path, including Kinnikuman and Natsuko. Kinnikuman eventually escapes after cutting Sokonashi-seijin's stomach open with his Kinniku Cutter. He later reappears as one of Kinkotsuman's minions.

Long Legged Gon (長足ゴン,Nagaashi Gon) is a Kaijū who has been harmlessly running around the world since ancient times. However, Kinnikuman has to stop him before he runs into a dam, causing massive damage. Knocked down by Kinnikuman, he is unable to stand back up because his arms are too small and he dies after three days. This tragic event causes Kinnikuman to appreciate jogging more.

Apollo the Giant (アポロ・ザ・ジャイアント) is a boxing Kaijū who easily defeats Kinnikuman. Kinnikuman receives training from a delusional Yosaku-san, who had been watching Rocky one too many times, and challenges him again. Kinnikuman manages to defeat him at the very last minute, resulting in several gym owners wanting Yosaku to train their boxers. He was named after Apollo Creed and modeled after André the Giant.

Burugorasu (ブルゴラス) is a Kaijū who attacks Japan while Kinnikuman is still touring America. Kinnikuman is allowed only thirty minutes to go to Japan and defeat him, if he cannot get back in time he has to return the Chōjin Olympic title. In the end, he defeats Burugorasu but does not make it back in time.

Monster Turkey (モンスター・ターキー) is, as his name suggests, a turkey Kaijū who attacks on Christmas. Kinnikuman and the Tanokin Trio argue over who will fight it. It is eventually defeated by Kinnikuman.

Gonta (ゴンタ) is a female gorilla Kaijū who tries to attack Bibinba, but is easily defeated by Kinnikuman. She is the sister of Gorizaemon.

Sprinterzord (スプリンタソード) is a robotic Kaijū that Kinkotsuman uses to attack an already weakened Kinnikuman. He had four legs and a serpent-like drill on his head. He is destroyed by Terryman's Magnum Gun attack, allowing Kinnikuman to focus on beating Kinkotsuman. In the anime he is renamed Neck Flinger (クビフリンガー,Kubi Furingā).

Tendon (テンドン) is a shrimp who is transformed into a Kaijū by Kinkotsuman and Iwao. He and his girlfriend Ebiko used to be part of a bowl of Tendon, but Kinnikuman was repulsed by it and instead threw Ebiko into the ground and smacked Tendon out of the house. Iwao found Tendon and gave him to Kinkotsuman, who used Tendon' desire for revenge to convince him to become a Kaijū. Tendon goes on a rampage until Kinnikuman defeats him, agreeing to eat him afterwards as a final request. Kinnikuman likes how Tendon tastes so much that he begins eating Tendon everyday instead of Gyūdon (by the next chapter, though, he's back to only gyuudon). He is voiced by Kouji Totani.

Bazoogara (バズーガーラー) is a Kaijū with bazookas (filled with Morinaga milk, Kinnikuman's weakness) on his back that Kinkotsuman uses to attack Kinnikuman and Terryman while giant/possessed Natsuko is on a rampage. Terry eventually subdues Natsuko long enough for Kinnikuman to destroy Bazoogara.

Ukon (ウコン) is an ape Kaijū who appears as the main antagonist during the Roots Island story. He turns out to actually be a robot piloted by Kinkotsuman and Iwao. He initially defeats Kinnikuman and takes over Roots Island, but Kinnikuman returns to fight him again. He is eventually destroyed by Mammora, and when Kinkotsuman and Iwao crawl out of the robot head Kinnikuman yells at them and scares them away. Characters named Ukon, very few of which have any simian features, appear in all of the Kinnikuman movies as minions of the film's antagonist. The running joke in the movies is that Kinnikuman always mishears his name as "Unko (うんこ,poop)", resulting in several poo jokes. He is voiced by Kouzou Shioya (movie 1); Kouji Yada (movie 2); Yudetamago (movies 3~6); Masaharu Satou (movie 7).

Octopus Dragon (オクトパスドラゴン) is an octopus Kaijū who Kinnikuman fights and defeats. A character named Octopus Dragon III appears as the main antagonist of the first Kinnikuman movie, but he possess an entirely different appearance and personality.

Harigorasu (ハリゴラス) is a Kaijū who Terryman fights and defeats. His body was spiny like a hedgehog and he would curl up into a ball and attack his opponent with his body. A character with the name Harigorasu appears in the first Kinnikuman movie and fights Rikishiman, although he looks entirely different. He is voiced by Yasurō Tanaka.

Mammora (マンモラー,Manmora) is a sacred mammoth Kaijū who helps Kinnikuman defeat Ukon. His name is a parody Mothra.

Miss Karasu (ミスカラス) is a bird-type Kaijū (karasu is Japanese for crow) who transports Kunta, Kinnikuman, Meat, and Terryman to Roots Island.

Because the volcano underneath the ring where first fought Kinnikuman erupts, the match ends in a draw. During the rematch, he counters Kinnikuman's 48 Killer Techniques with his own 96 Killer Techniques and gains the advantage. In addition to Kinnikuman's, he also has variations of the other Seigi Chōjins techniques.

The character "祖" is written on his forehead and his face greatly resembles Tatsunori's. While washing his alternate mask in a river one day, he accidentally dropped it. As he raced after it, Kami-sama appeared and asked The Golden Mask or this Worn Out Mask, which did you drop?

Furthermore, in Kinnikuman Nisei it is established that he created the Niku Curtain and founded the Royal Kinniku Family. His name comes from Tatsunori Hara. He is voiced by Akira Kamiya.

Uldraman (ウルドラマン) is the 18th Chōjin Olympics Champion. He is very prideful and was once Japan's main Chōjin, but he retires after a humiliating defeat at the hands of Robin Mask at the 19th Olympics (according to a flashback in Kinnikuman Nisei, his hip is broken in half by Robin's Tower Bridge, ending his career). Despite seeming to be a big wheel Chōjin, he is never seen after this (excluding the flashback). He was originally called (and meant to be) Ultraman, but this was later changed for copyright reasons. In the anime his name was Uttraman (ウットラマン). It is unknown if he is one of the Ultra Brothers.

Shigeru-kun (シゲルくん) was a young man of the Giant Clan who the Royal Kinniku Family adopted to replace the less impressive Kinnikuman. He is later said to have been "adopted" into the Tiger Clan of Planet Tigers. However, he never appears after this. His name comes from former professional baseball player Shigeru Kobayashi, and his adoption itself is a parody of the Suguru Egawa Incident. In the anime he is replaced by Tatsunori-kun (タツノリくん), who is modeled after Tatsunori Hara.

Medium Rare (ミディアム・レアー) is Meat's very beautiful older sister. Her fiance Salami is held hostage by Dai King, but with her help Kinnikuman rescues him. In Kinnikuman Nisei her name is written as Rare Alexandria (アレキサンドリア・レアー,Alexandria Rare).

Horumon himself has challenged and lost to Mayumi Kinniku countless times, and his wife Harami was killed by the Kinniku Clan. In order to seek revenge on the Kinniku Clan, he sends his daughter Bibinba and Shishkeba Boo of the Barbecue Clan as assassins, but both of them fail. In Kinnikuman Nisei he appears as one of four great elders of Planet Kinniku's Chōjin Council (超人評議会). He seems to have reconciled since Bibinba married into the Kinniku Clan. His name comes from horumonyaki. He is voiced by Jōji Yanami.

Shishkeba Boo(シシカバ・ブー) is a member of the Barbecue Clan (バーベキュー族,Baabekyuu-zoku). The champion of the Galactic Chōjin Carnival, he agrees to kill Kinnikuman for Horumon Yaki in exchange for Bibinba's hand in marriage. He defeats Kinnikuman and almost kills him (in the anime film they are equal), but after seeing how deeply Bibinba cares for him he backs away like a man. Although very manly and strong, he has a quite homely face, even funnier looking than Kinnikuman's. However, whether or not his clan wears masks like the Kinniku is unknown. He is voiced by Keiichi Noda, Mahito Ōba (Nisei).

Beansman (ビーンズマン) is a disciple of Ingen and a young boy from Planet Rakka (ラッカ星,Rakka-sei), a parody on rakkasei, the Japanese word for peanut. When Planet Rakka is invaded by the Uchuu Nobushi, he heads for Earth in order to gather Chōjin like Terryman for help. He collects kaijū and carries around one named Monster #1.

Ingen (インゲン) is the great elder of Planet Rakka. In order to combat the Uchuu Nobushi invasion, he sends Beansman to Earth to find Seigi Chōjin. He seems to be somewhat immortal, as he survives having an arrow pierce his head and is also rather clam with it still in his head. He is voiced by Jōji Yanami.

The Uchuu Nobushi (宇宙野武士,Space Samurai) are a group of invaders who attack Planet Rakka. The only reason they pause from fighting is to eat. After Crystalman finds the weakness to their Combine and Enlarge technique, they are destroyed by Kinnikuman and the Chōjin Team. In the TV Special, the actual leader is identified and named Black King (ブラックキング).

Kinnikuman Mariposa (キン肉マン・マリポーサ), originally Thief George (盗人ジョージ,Nusutto Jooji) was one of the Five Fated Princes (運命の五王子,Unmei no Go Ouji). In the anime he is voiced by Masaharu Satou, and Thief George is voiced by Sho Hayami.

The future Kinnikuman Mariposa was born on the same day and in the same hospital as Kinnikuman and four other young boys, but because of a fire the children were mixed up and the true heir of their home planet may have been misplaced. His family moved to Planet Moctezuma (モクテスマ星,Mokutesuma-sei), a planet with an atmosphere so thin its inhabitants were forced to wear oxygen masks. Because of this, he grew up with a tough heart and amazing jumping abilities, and because he also grew up poor, he soon turned to a life of theft. While living as a thief, he stole the Robin Family heirloom the Anoalo Sceptre (アノアロの杖,Anoaro no Tsue), a item capable of controlling flames. After Kinnikuman had proven himself worthy to become the next king of his home planet, five evil gods sought out the other potential heirs and gave them great Chōjin power to become the Five Fated Princes, who all claimed to be the true heir. Mariposa was chosen by the God of Flight (飛翔の神,Hishou no Kami). A royal survivor series was organized to determine who was worthy of ascending the throne. Kinnikuman Mariposa's team fought the true Kinnikuman and his allies in the first round in Kumamoto Castle. Mariposa ended up fighting Robin Mask himself, making use of the stolen staff. He was stunned by a beam from a temple on Planet Kinniku when he tried to use a fake Muscle Revenger, a sacred technique used by the Kinniku Royal family, and was ultimately beaten by Robin's Robin Special, giving him his revenge.

Mister VTR (ミスターVTR) is a camera-type Robo Chōjin. He uses various image-using special techniques. While posing as a relay camera he records the fight between Kinnikuman and The Hawkman and afterwards fights and loses to Kinnikuman. However, after his defeat and right before he dies he takes the footage he had recorded of the Kinniku Driver and edits it, contributing to Mixer Taite's victory. Submitted by a fan as Mac Star (マックスター). He is voiced by Toshio Kobayashi.

Mixer Emperor (ミキサー大帝,Mikisaa Taitei) is a blender-type Chōjin. Kinnikuman fails to defeat him (however, this is because both Mister VTR and the Evil Gods lent him some of their power in a 7-on-1 gang-up). With his Power Separator he removes Kinnikuman's Kajiba no Kuso Chikara from his body. However, he doesn't notice when Kinnikuman removes one of his screws shortly before. Because of this, Meat is able to shatter him with a Back Drop. He is voiced by Yasuhiko Kawazu.

King the 100 Ton (キング・ザ・100トン,King Za Hyaku Ton) is a weight-type Chōjin. He possesses a 100 Ton metal body, making him the heaviest Chōjin in the series. His weight body is divided into different parts, allowing him to adjust his weight according to the situation in fights. His body can also transform into iron balls, barbells, and other things, but this requires images from the outside (special cards with a picture of the object on it). He overwhelms Meat with his weight but Terryman takes advantage of his transformations by causing his molecules to rearrange so he can shatter his body with his Calf Branding. However, after the match, he uses the last bit of his power to knock out Terryman, making the match end in a draw. He is voiced by Kazuo Oka.

Kinnikuman Zebra (キン肉マン・ゼブラ), originally Powerfulman (パワフルマン), was one of the Five Fated Princes (運命の五王子,Unmei no Go Ouji) from the final story arc. In the anime he is voiced by Hirohiko Kakegawa. His name comes from the zebra-stripe pattern covering his body.

Powerfulman, who would be Kinnikuman Zebra, was born in a hospital on planet Kinniku in the same day as the real Kinnikuman and four other boys, but because of a fire the children were mixed up and the true heir to the throne of their planet may have been given to the wrong family. Powerfulman grew up in Africa, where he worked as a farmer to earn money to buy his way into the Chōjin Society. His only friend during this period of his life was his pet zebra Zebra Kid (愛馬キッド,Shimauma Kiddo). When he went to gain admission by offering the 9,000,000,000 Chōjin Dollars he had earned, he was denied but then offered admission if he killed Kid. He did so and from then on, he trusted only those who live for money (in fact, he paid each of his team members 3,000,000,000 Chōjin Dollars to fight for him).

When the true Kinnikuman proved himself worthy to ascend the throne of planet Kinniku, five evil gods who feared the power he would have decided to seek out the other possible heirs and give them Chōjin power in order to turn them into the Five Princes of Fate and oppose his claim to the throne. The God of Technique (技巧の神,Gikou no Kami) chose Powerfulman, and turned him into Kinnikuman Zebra. Unsure who truly was the proper heir, the current royal couple arranged a survivor series, with whoever won becoming the next king. Zebra and his teammates were given a buy into the second round of the tournament. They fought against Team Kinnikuman at Himeji Castle. Zebra took part in a tag match with Parthenon against Kinnikuman. He is usually a clean fighter (White Form), but when he steps into Parthenon's shadow his stripes cover most of his body and his brutal side emerges (Black Form). After Parthenon is defeated by Robin Mask, he offers Robin and Ramenman 5,000,000,000 Chōjin Dollars to help him in the finals, but they instantly refuse. Because Kinnikuman's Kajiba no Kuso Chikara had been sealed, he was able to defeat the Kinniku Driver. He almost defeated Kinnikuman with the Muscle Inferno, but the spirit of Kid arrived and helped Kinnikuman escape it and defeat Zebra with an Incomplete Muscle Spark. Although Zebra survives the fight, as he is being carried away on a stretcher, Kinnikuman Super Phoenix's teammate Prisman blasted him with his Rainbow Shower attack, and Zebra is disintegrated to his skeleton. It is interesting to note that in the anime, this never happens. Zebra simply disappears after his fight with Kinnikuman.

Teammates of Kinnikuman Zebra

The Manriki (ザ・マンリキ or ザ・万力) is, as his name indicates, a scramble vice protrudes from his shoulders which he uses to crush opponents. It is powerful enough to crush steel and diamond and can also grow from areas other than his shoulders. His head is also very strong, as it was not affected when hit by the Screw Driver. He dominates Meat but then faces the recently revived Warsman. At first Warsman forgets his fighting style and is overwhelmed, but he is eventually defeated with the Palo Special. He is voiced by Masaharu Satou.

Motorman (モーターマン) is the power source for Robo Chōjin Bikeman as well a member of Team Zebra. He has a very simple design with a drill-shaped head, batteries for hands and feet, and a motor body. He easily dominated Terryman, but he revived Ramenman's fighting intuition and was ripped in half by the Camel Clutch. He is voiced by Yasuhiko Kawazu.

Bikeman (バイクマン,Baikuman) was a Machine Chōjin in the form of a motorbike and served as Kinnikuman Zebra's Center Guard. At first, he was called Riderman (ライダーマン), but a character with the same name appeared in Kamen Rider V3, so it was changed to'Bikeman. He has a dangerous personality and shakes with excitement during a rough fight. He is usually shaped like a normal human, but he can transform into the shape of an autobike. He could also manipulate electricity at will. Zebra relies heavily on his fighting abilities. He charges up his engine by plugging into his teammate Motorman. Like his teammates, he refers to Zebra as Zebra-sama (ゼブラさま). He is voiced by Masato Hirano.

Parthenon (パルテノン) is modeled after the real-life temple Parthenon. His shadow has the power to bring out Zebra's brutal personality. His entire body is made up of sculptures. Thousands of dead creatures are inside his temple body, and his pillars are filled with methane gas. He was offered 3,000,000,000 Chōjin Dollars to perform on Zebra's team. The dollar bills (gold bars in the anime) he received from Zebra were packed into his pillars. In the last semifinals match of the Survivor Match for the Kinniku Throne, he teamed up with Zebra in a Tag Match against Kinnikuman and Robin Mask. He trapped Robin inside his pillars with his "Body Petrification Trap", but Robin escaped using the Anoaro Staff. He then broke Parthenon in half with his Tower Bridge and finished him off with the Robin Special. He is voiced by Masaharu Satou.

Puri-Puri Man (プリプリマン, Monsieur Cheeks in the English dub) is one of the few characters from Kinnikuman to not have a M.U.S.C.L.E. or Kinkeshi figure. Puri-Puri Man (literally "angry smelly man") appeared in one panel of the manga when Buffaloman's Akuma Chōjin attacked Kinnikuman. He also appears twice during the original opening of the Kinnikuman anime. His name appeared as the 51st place in the train tossing event in the original Kinnikuman manga; this may indicate that he was not actually one of the Akuma Chōjin.

Planetman (プラネットマン) is one of the Six Devil Knights (悪魔六騎士,Akuma Roku Kishi) who serve under Akuma Shogun. Known as Uchuu Jigoku (宇宙地獄,Space Hell), he uses space themed wrestling. His body was made up of the nine planets of the solar system. Originally appearing as a masked Chōjin, his true face is later revealed to be the legendary Planet Vulcan. Although his space wrestling is quite powerful, he is not above using cowardly and unfair tactics, such as his Face Planet technique. Like the other Devil Knights, he possessed a Golden Mask (黄金のマスク,Ougon no Masuku) which Kinnikuman was supposed to fight him for. He is voiced by Hideyuki Tanaka.
